How many times have you started a round, played a few holes and wished you could just go back to the first tee and start over? That's what the PGA Tour did today.

The third round of the Deutsche Bank Championship got under way as planned this morning, but rain and lightning brought play to a halt around 8:45 a.m. ET. After the weather finally cleared up a couple hours later, officials decided to throw out all the scores and restart the round from scratch.

Zach Johnson and Stuart Appleby, in the first group, had reached the sixth hole when play was halted. A total of 14 players had teed off.

The restart also saw the players re-paired – instead of twosomes off the first tee as originally planned, they were grouped in threesomes off both the first and 10th tees at TPC Boston. They also are being allowed to lift, clean and place their balls.

If you're wondering, this is the second event this season in which the PGA Tour has re-started a round – it happened twice at the season-opening Hyundai Championship in January.

The threat of scattered thunderstorms remains this afternoon, and actually the chance of rain increases as the afternoon goes forward, according to the PGA Tour.

Monday's forecast also calls for a 60 percent chance of rain, and as a result, the final-round tee times already have been moved up. The players again will be grouped in threesomes off the first and 10th tees, with tee times running from about 8:00-10:00 a.m. ET.
